Swift A-Frame Heavy Rifle Bullets in .458 caliber, 450 grains (Swift part no. 454506), step up in weight from Swift’s 400-grain loading for handloaders who want maximum penetration on the heaviest and most dangerous game. The A-Frame design pairs a cross-member copper jacket with a bonded front core to deliver controlled expansion, roughly 95 percent weight retention across velocities, and deep penetration. Construction includes a soft semi-spitzer lead nose to protect against felt recoil in the magazine, a tapered jacket around a pure lead core to control expansion rate, and a wraparound base jacket that resists deformation. Swift builds this uncoated bullet to outperform the competition on retained weight and penetration.
